| ❌ Mistake | ✅ Correct Approach |
|---|---|
| Overtightening the assembly, leading to O-ring extrusion or excessive compression. | Tighten fasteners to the manufacturer's specified torque values to ensure proper compression without overstressing the O-ring. |
| Using incompatible cleaning agents that degrade Buna-N material. | Clean O-rings and grooves with mild soap and water or a compatible solvent recommended for Buna-N. Avoid aggressive chemicals. |
